FG Knowledge Base - Firewalls

[ivan-hr]

Thanks and sorry.

I had problems with the port. I am running FG2 thru Steam on OS X.

I am using a FritzBox 6320 and an TL-WR840N Wireless Router. I had to add a port forward in each device to make FG2 use port 1802.

Hope that helps anyone else with the same problem.

Well done ivan-hr.
Having a router/modem and a wifi/router crops up a bit and yes you have to do what you did there.
You are also lucky - many Germans dont get an IPv4 address and have to use Hamachi/Tunngle/VPN to get it to work.

Hello all you smart people,

I recently bought a new computer and have successfully merged all our old campaign onto the new machine. The cable modem and router did not change. However the test function keeps giving me a failure. I have Win 10 now. I remember I had to do something internally to the computer to get FG to run but I can not remember what. I have turned off the windows firewall, and tried to do the IP4 static IP address fix still with no luck.

Any ideas?

Zeff

Hi All,

I recently took a stab at fantasy grounds ultimate and am having some issues with the connection test and can you see me. I keep receiving the failure on the test and connection refused on canyouseeme. I have tried canyouseeme with a session running and without.

I am running an arris modem/router with an asus rt n16. I have forwarded port 1801-1803 on the arris (also have tried just 1802) to the asus and then forwarded the 1802 port on the asus to my pc's static ip address. I have instructed windows firewall to port 1802(TCP) for fantasy grounds. I have tried disabling all firewalls and shutting down antivirus (temporarily for science of course). I tried a direct connection to the arris without a firewall and receive the same connection refused.

Anyone have a bit of time to help me out?

Hey Dalamar - we are in different timezones but PM me when you are online next and Ill help you out. You sound like you are totally on the right track and may have just messed a step along the way. Its definietly only TCP and 1802. Any other ports and protocols are red herrings. You do need arris -> asus -> pc (if the ASUS WAN is plugged into the ARRIS LAN - if the ASUS LAN is connected to ARRIS LAN then you just do Arris -> PC).
Its TCP1802 at each step and best to have DHCP reservations along the way too.

Hello, all. I've just moved into a new apartment, and I'm now getting connection problems setting up an FG host. Previously, I had a cable modem and router, and single port forwarding worked just fine. My new place uses Webpass as a provider, so no more modem on my end. Just the router.

However, the single port forwarding no longer works for the router. I've tried a few things, including a direct hardwire connection with firewalls off (temporarily), and still the test fails and the canyouseeme.org test also fails. I suspect it's related to this news from Webpass posted in June of last year:

Webpass allocated the final available residential IPv4 address space assigned to us today. All residential buildings coming online after today will receive a private IPv4 address space. Existing residential buildings with public IPv4 assigned will slowly transition to private IPv4 addresses as demand exceeds the currently allocated IPv4 address space. We expect minimal impact for all customers. The entire Internet will still be available when surfing the web from your Webpass connection. However if you wish to connect to your Webpass connection from a remote location (for example you have a web camera in your unit) the connection will only work on the IPv6 protocol.

I could be wrong, but every place I've been able to touch (or remove) from the chain between FG and the internet, I've touched (I've also confirmed localhost connections work, but connections from a second laptop do not). This is the only piece I can't touch, but if anyone has any suggestions or experience, I'd appreciate it.

(I've also downloaded Hamachi in anticipation of having to use it as do satellite-using GMs)

Thanks.

therealSamael7 you are out of luck. Hamachi or a VPN (that allows direct access to the public IP address) is required.
FG Next (whatever it will be called) will most likely (it should!) support IPv6 but the current game engine does not.
You can if you like have a look at this doc and build a VPN server for $10/year and a little elbow grease.

The only condition on using this is proofing the doco to make sure its right and works as written.

Edit: Hamachi is your easiest option by far - but it will require the players to also use Hamachi (which I dont think is a big deal). The VPN option removes that step for the players but puts more onus on you.

Thanks! I suspected this would be the case. The good news is I've got Hamachi going and had my first player connect. Appreciate your input. Cheers!
